Embodiment 1

[0035] figure 1 It is a flow chart of the method for detecting the dryness of clothes for the clothes care machine described in this embodiment, refer to figure 1 The method for detecting the dryness of clothes for the clothes care machine of this embodiment is described in detail, which mainly includes the following steps:

[0036] S110. Detect the background temperature, and detect the surface temperature of the clothes at the clothes detection point.

[0037] The body of the clothing care machine is equipped with an infrared temperature detection module, through which the temperature signal of each detection point is detected, and the measured temperature signal is sent to the controller, which generates a corresponding temperature value.

[0038] Wherein, the upper inner wall that cannot be blocked by the clothes in the body is selected as the background temperature detection area, and the side of the clothes opposite to one of the two opposite side walls in the body is s...

Embodiment 2

[0049] The method for detecting the dryness of clothes for a clothes care machine described in Embodiment 1 is mainly applicable to the N clothes detection points where the corresponding positions can be found on the dry clothes in the clothes care machine, that is, the area of ​​the clothes to be dried is relatively large; but For clothes with a small area, some of the clothes detection points used to detect the surface temperature of the clothes are actually not covered by clothes, and the detected temperature is the temperature of the inner wall surface of the clothes care machine. For clothes with a small area, in the process of actually detecting the dryness of the clothes, the difference between the background temperature and the surface temperature of the clothes at the beginning of drying will be △T 1 The number of clothes detection points less than the first preset value T1 is too large, which may cause false determination that the clothes are dry.

[0050] In view of...

Embodiment 3

[0082] The difference between this embodiment and the first embodiment is that according to the difference ΔT between the background temperature and the surface temperature of the clothes 1The relationship between the ratio of the number A of the clothes detection points greater than the first preset value T1 to the N clothes detection points and the preset ratio determines whether the clothes have been dried. Specifically, the preset ratio is K / N, if A / N

[0083] The values ​​of K and N described in this embodiment are the same as those in Embodiment 1, that is, K=16, N=256.

Abstract

The invention relates to the field of clothes dryness detection, and specifically discloses a method for detecting clothes dryness for a clothes care machine. The method comprises the following steps:detecting background temperature, detecting clothes surface temperature of a clothes detecting point; and determining whether clothes is dried according to the background temperature and the clothessurface temperature. The method determines whether clothes is dried according to the background temperature and the clothes surface temperature through detecting the background temperature and the clothes surface temperature of the clothes detecting point. The method for detecting clothes dryness for a clothes care machine solves a delay problem in an existing dryness detection method, and improves detection efficiency.

Description

technical field [0001] The invention relates to the field of methods for detecting the dryness of clothes, in particular to a method for detecting the dryness of clothes for a clothes care machine. Background technique [0002] In the existing clothes care machine, the clothes are hung in the treatment room, the clothes are ironed or deodorized by steam, and then dried by hot air, and the dryness detection is performed during the drying process to determine the dryness of the clothes. A conventional dryness detection method is: using a detection circuit to determine the dryness of the clothes by detecting changes in the electrical conductivity of the clothes. [0003] However, when using clothes care for drying, the clothes are hung up, so the principle of conventional dryness detection cannot be used for detection, but the change of the temperature of the clothes is used to determine the degree of dryness of the clothes. , the absorbed heat is reduced, and the rate of chan...
